FAQs
For a proper installation, locate the transformer in a ventilated electrical room with adequate clearance for cooling and servicing. Mounting should align with its 17.75 in depth, 21.88 in width, and 28 in height footprint, and allow for access to the UL Listed enclosure. Ensure connection to a 480 V three-phase source and the 480Y/120/208 secondary wiring per local codes. Use proper lugs, torque settings, and protective devices; verify DOE2016 Efficient compliance during commissioning.
The K-Factor nonlinear design reduces harmonic-related losses and power quality issues, improving load performance and reducing transformer heat. This translates to cooler operation, extended insulation life, and lower cooling energy. In practice, facilities with variable motor loads and drives see steadier voltages and currents, contributing to higher overall efficiency and lower energy costs over the life of the transformer.
Yes. With a 15 kVA rating and a 480 V primary feeding a 480Y/208/120 secondary, this transformer is well-suited for data centers and IT rooms requiring reliable, clean power and tight voltage regulation. The UL Listed certification and DOE2016 Efficient compliance help meet facility standards, while its ventilated design supports high-density racks and modular deployments.
This transformer is UL Listed and complies with DOE2016 Efficient standards. These certifications verify electrical safety, energy efficiency, and regulatory alignment for commercial and industrial environments. Choosing UL Listed equipment also simplifies insurer and contractor approvals, while DOE2016 Efficient reduces energy waste and cooling demands in sensitive facilities.
Expect lower maintenance costs due to reduced heat generation and improved reliability from the K-Factor design, plus energy savings from DOE2016 Efficient operation. The transformer’s robust enclosure and solid Eaton support ecosystem improve uptime and serviceability, enabling faster material returns on investment and a clearer total cost of ownership for mission-critical facilities.
